cant turn a viscous fan off when wading
You don't need to. The viscos will just stop turning when there is sufficient resistance. I've never found it a problem.

except , when locked up, it dont like being stopped. I have seen one shed its blades through the radiator

@gstuart and @Mr S1

Have fitted a fan recently, may be of help.

Cheers

Have indeed !

Me and @gstuart fitted a Revotec one, full kit from Revotec. Being honest the instructions are a bit s**t, Gary fortunately is good with electrics and we ultimately decided to plumb in a separate loom for the fan as splicing into the loom can open a proper can of worms. Separate cables behind the dash and through the bulkhead into the engine bay. I bought the separate fuse from Revotec (which ultimately we didn't use as Gary preferred to use a separate fusebox we fitted into the battery bay). We also used the separate on / off switch from Revotec which allows me to be in control of it as opposed to relying on the thermostat supplied (fully adjustable).

The wiring and working out the electrics were by FAR the biggest part of the job, but a top bit of kit and works a treat. Really pleased with it, and I'm still offering big thanks to Gary for his expertise ! No qualms in admitting it wouldn't have happened were it not for him !

I would guess they must have hit the water at a speed and engine revs far in excess of recommendations for that to have happened.

Strange you should mention that, the instructions with the Kenlowes were a bit Sh!t as well.

I found with a viscos fan the temperature gauge just sits about one third up the temp gauge and just sits there come what may. With the Kenlow the temp was up and down with the fan tripping in then bringing the temp down. I'm far happier and feel more confident with the viscos. Electric fans break down and often have electrical problems also. Having ran both I wouldn't go electric again.

Do you have a shroud fitted? I've considered putting a viscous fan back on and trying to improvise a shroud, but the leccy fan would be easier.

Nope, just the viscous fan and a big gap and the standard 300tdi shroud. It must shift some air, but I suppose some of it must get sucked from beneath the rad rather than through it.
I find that the TDi runs much cooler than the 2.5 N/A that it replaced, possibly because it isn't being driven flat out all the time.

Tdi just run cooler, even with both on idle. I would guess due to greater efficiency and slightly lower compression ratio of the Tdi.

many thks, it was indeed a challenge trying to follow the wiring diagram they provided which was useless,

hopefully manufacturers will improve there instructions as blimey they were hard to understand , seeing some were listing a permanent live on one instruction and a switched live on another , lol

is always a great pleasure to help u kind sir ,

The bit about mounting seemed to be for another vehicle, and made no mention of the fact that I would have to fabricate a frame and mounting brackets from scratch to assemble the twin fans behind the rad.

I fitted a slim line electric fan off ebay for about 20 quid. Couple of bat straps from a builder friend chopped down to height and tie wrapped the fan to the holes in that. I wired it into a three way switch so I can have it on off or thermostatic controlled and the thermostat I got from a scrap yard off a Peugeot.. My mate has his on an on off switch and barely uses it.
